Is sedation required for intubation?: Intubating patients who are not sedated is difficult and can be dangerous. The patient’s gag reflex can cause movement of the airway and regurgitation of vomit or secretions into the airway causing complications. The vocal cords can also spasm during non-sedated intubation causing damage to the cords and complicating the procedure.

Chronic Obstructive Pulmonary Disease (COPD)

Chronic obstructive pulmonary disease (COPD) is a lung condition in which there is a long-lasting obstruction of the airways, and occurs with emphysema, chronic bronchitis, and/or asthma. Causes of COPD include cigarette smoking, exposure to secondhand smoke and environmental tobacco smoke, Alpha 1-antitrypsin deficiency, airway hyper-responsiveness, and air pollution. Symptoms of COPD include a productive cough and acute chest illness, shortness of breath, wheezing, heart failure, cyanosis, and weight loss. Treatment of COPD includes medications, oxygen therapy, surgery, and lung transplant.
Procedural Sedation vs Moderate Sedation

Procedural sedation refers to the process of administering sedatives or dissociative agents with or without pain relievers/blockers (analgesics/anesthetics) to result in lowered consciousness to allow patients to tolerate medical procedures while maintaining breathing and keeping their airway open on their own.
sedation vs general anesthesia difference

Sedation is a sleep-like state where patients are generally unaware of surroundings but may still respond to external stimuli. General anesthesia is a form of a temporary medically induced state of unconsciousness in which pain control and amnesia are induced, and patient’s airways may be taken over and monitored by a doctor, rather than patients breathing on their own.
